With the rapid development of electronic technology, automatic control systems are used more and more widely in all aspects of power production. While electric workers benefit from the great convenience of microelectronics technology, they are also troubled by huge losses once they are damaged. In fact, when the automatic control system is added to the power system, the awareness of the safety and lightning protection of the automatic control system is relatively weak. Once the lightning wave invades, the equipment damage is generally huge, and some even paralyze the entire system, causing irreversible Loss.
